Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the main part ASE-27.000MHZ-L-R-T.

ASE-27.000MHZ-E-T (Abracon LLC): This substitute exhibits wider frequency stability tolerance (±100ppm) and narrower operating temperature range (-20°C ~ 70°C). Selection is appropriate for applications where the reduced temperature range and relaxed frequency stability are acceptable.

ASE-27.000MHZ-L-C-T (Abracon LLC): This substitute maintains identical operating temperature range (-40°C ~ 85°C) with moderate frequency stability (±50ppm). This part provides intermediate performance characteristics between the main part and ASE-27.000MHZ-E-T.

SXO32C3C481-27.000M (Suntsu Electronics, Inc.): This substitute matches the main part's frequency stability (±25ppm) and operating temperature range (-40°C ~ 85°C), with lower maximum supply current (10mA versus 13mA). Cross-manufacturer substitution is supported by identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can ASE-27.000MHZ-E-T replace ASE-27.000MHZ-L-R-T in all applications?

A: ASE-27.000MHZ-E-T is compatible for applications operating within -20°C ~ 70°C temperature range. Applications requiring operation below -20°C or above 70°C require the main part or ASE-27.000MHZ-L-C-T.

Q: What is the difference between ±25ppm and ±100ppm frequency stability?

A: Frequency stability defines the maximum deviation from the nominal 27 MHz frequency across operating conditions. ±25ppm allows ±675 Hz deviation; ±100ppm allows ±2700 Hz deviation. Applications with stringent frequency requirements require ±25ppm or ±50ppm stability.

Q: Is SXO32C3C481-27.000M from a different manufacturer compatible?

A: Yes. SXO32C3C481-27.000M from Suntsu Electronics, Inc. matches all critical electrical and mechanical parameters, including frequency, output type, supply voltage, package dimensions, and operating temperature range. Cross-manufacturer substitution is supported.

Q: Does packaging format affect substitution?

A: The main part ASE-27.000MHZ-L-R-T is supplied in Tape & Reel (TR) packaging. ASE-27.000MHZ-E-T and ASE-27.000MHZ-L-C-T are also Tape & Reel. SXO32C3C481-27.000M is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection depends on procurement and assembly requirements.

Q: What does Enable/Disable function mean?

A: Enable/Disable function allows the oscillator output to be controlled via an external pin, enabling power management by stopping oscillation when not required. All listed parts support this functionality.

Q: Are all parts RoHS compliant?

A: Yes. All parts listed are ROHS3 Compliant, meeting regulatory requirements for hazardous substance restrictions.
